Paul Tucker

The Deputy Governor of the Bank of England encouraged Barclays to try to lower interest rates after coming under pressure from senior members of the last Labour government, documents have disclosed.

A memo published by Barclays suggested that Paul Tucker gave a hint to Bob Diamond, the bank’s chief executive, in 2008 that the rate it was claiming to be paying to borrow money from other banks could be lowered.

His suggestion followed questions from “senior figures within Whitehall” about why Barclays was having to pay so much interest on its borrowings, the memo states.

Barclays and other banks have been accused of artificially manipulating the Libor rate, which is used to set the borrowing costs for millions of consumers, businesses and investors, by falsely stating how much they were paying to borrow money.

The bank claimed yesterday that one of its most senior executives cut the Libor rate only at the height of the credit crisis after intervention from the Bank of England.
